14 Claims. (Cl. 242-25) This invention relates to improvements in wire spooling mechanisms, and more particularly to a spooler attachment adapted to be applied to the end of a high-speed continuous wire drawing machine.

One object of this invention is to provide a spooler attachment of the above nature in which the wire spool is adapted to be driven by means of a constant speed endless belt which is pressed the above nature, which will be relatively simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, and very eflicient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawings one form in which the invention may be conveniently embodied in practice.

avoiding tracking, and automatically compensating for irregularities in the spooling.

Referring now to the drawings in which like referencenumerals denote corresponding parts throughout the several views, the numeral I3 indicates a continuous wiredrawing machine of the type disclosed in a prior application by the same inventor entitled Multiple wire drawing machine, Serial No. 514,381, filed February 9, 1931. The numeral I I indicates the final drawing die through which the wire I2 is adapted to pass to a final drawing roll I3 mounted on the forward end of a spindle shaft I4, said shaft I4 being journaled in an extension box I5 connected with the right end wall of the wiredrawing machine I0.

As the finished wire I2 leaves the final drawing roll I3 it will travel in an upwardly inclined direction to a small guide pulley I6 carried on the free end of an overhead spring balance arm I1, and thence in a downwardly inclined direction to a winding spool I8 to be described later.

The balance arm I1 is rigidly secured at its inner end to a horizontal pivot shaft I9 journaled in the upper end of an angular upright bracket which may be securely fastened to the end wall of the wire drawing machine l0. The arm I1 is adapted to be balanced by means of a helical spring 2| having tangential connection with a pair of grooved pulleys 22 and 23. The grooved pulley 22 is keyed to the pivot shaft I9, while the pulley 23 is rigidly mounted on a pivot stud 24 located at the bend in the angular upright bracket 20. The tension of the spring 2I may be readily adjusted for more or less resistance by manual manipulation of a knurled knob 25 integral with an adjusting shaft 26 having tangential screw and gear connection (not shown) with the pivot stud 24 of the grooved pulley 23.

In the operation of the spring balance mechanism just described, it will be understood that the wire I2 passing over the balance pulley I5 will maintain a substantially constant speed. This is due to the fact that any slight irregularities which may occur in the tension of said wire I2 as it comes from the wire drawing machine I0 on its way to the spool I8 will be automatically compensated for by the spring-balance arm I1. Thus, it will be seen that any slight momentary increase of the wire tension will cause the arm I1 to instantly rock downwardly, while, if the tension in the wire should be momentarily diminished, the reverse action will occur.

Winding spool mechanism The winding spool I8 is provided with a pair of parallel end anges 21 and 28, and is adapted to be removably supported upon a pair of free running stud spindles 29 and 38. The rear stud spindle 30 is suitably journaled in a ball bearing, not shown, contained within an enlarged longitudinally adjustable hollow hub 3l, and said spindle 30 is also provided with an integral intermediate flange 33a adapted to abut against the spool flange 26. The hollow hub 3I is integrally connected to a pedestal 32 which is attached to the top surface of a horizontal bed plate 33 forming a part of a large support bracket 34, attached to the sidewall of the extension box I5 as by a plurality of cap screws 35. The hub pedestal 32 is provided with a pair of elongated slots 36 and 31 by means of which the hub 3I maybe longitudinally adjusted to any position within the limits of said slots 36 and 31 and then fastened in position, as by bolts 36a and 31a.

The forward or outer flange 21 of the spool I8 is adapted to abut against a ange 29a formed upon the stud spindle 29, the inner end of which is detachably centered within said spool I8. The outer end of said spindle 29 is enlarged and fitted within a ball bearing 38, being secured to the inner race thereof as by a locking nut 38a. The outer race of said ball bearing 38 is secured with,- in an enlarged hollow hub 39 by means of an end cap 4B.

The hub 39 is provided with a downwardly extending flanged arm 4I formed integral with a sliding adjustable tail stock member 42, whichA is adapted to slide upon a forwardly extending stationary support shaft 43 attached to a round boss 44 forming a part of the support bracket 34. The lower part of the tail stock 42 is provided with a depending split boss 45 for receiving a transverse screw stud 46 operated by a depending handle 41, and by means of which said tail stock 42 may be locked in any adjusted operating position on the support shaft 43.

In the operation of removing the spool I8, the tail stock 42 will first be pulled forwardly as far as it will go (to the left as shown in Fig. 3) the arm 4I may then be swung laterally about the axis of the support shaft 43 in a clockwise direction as viewed in Fig. 1, so as to permit the spool I8 which has just been filled with wire to be manually removed from the supporting stud spindles 29 and 30 and be replaced with an empty spool. The flanged arm 4I will then be swung upwardly in the opposite direction until a lateral stop lug 48 carried by the tail stock 42 strikes an elongated stop pin 49 extending forwardly from the boss 44.

The tail stock 42 will next be pushed to the right, sliding upon the support shaft 43, to the operating position shown in Fig. 3, being guided in its sliding motion by a lateral apertured guide lug 5I extending rearwardly from the tail stock 42 and adapted to be centered upon a short guiding shaft 52 secured in any suitable manner to the support bracket 34. The flanged arm 4I will likewise be limited from swinging too far in a clockwise direction by another lateral stop lug integral with the tail stock 42 and adapted to abut against the stop pin 49.

Spool driving belt mechanism The winding spool I8 is adapted to be driven by means of a constant speed endless belt 53, preferably made of canvas or like material, the upper course of which is adapted to contact with the wire being wound on said spool I8. The endless belt 53 is mounted around a. pair of broad flangeless pulleys 54 and 55 which are adapted to be journaled to the opposite forked ends 56 and 51 of a swinging cradle 58.

The left hand pulley 54, as viewed in Fig. 1, is the driving pulley and is rigidly secured upon a driving shaft 59 by means of a feather key 59a. The shaft 59 is journaled on a xed axis in ball bearings 60 and 60a contained in a pair of stationary hollow bearing housings 6I and 62, said housings being formed integral with the rear edge of the bed plate 33. In order that the driving pulley 54 may be driven in synchronism with the wire drawing machine I0, the shaft 59 is adapted to receive power by means of a small pulley 63 fastened to the rear end thereof, and connected to a large driving pulley 64 as by an endless belt 55.

The driving pulley 64 is secured to the rear extremity of the drawing roll spindle shaft I4 Orff IJlI as by a retaining nut 64a. The spindle shaft I4 is mechanically connected by means (not shown) within the extension box I5, to the same source of power, not shown, that drives the wire drawing maclrine I6.

The xed forked end 56 of the swinging cradle 58 is provided withl a pair of integral hollow hubs 89 and 81 within which are a pair of ball bearings 68 and 69 for journaling the driving shaft 59, as best shown in Fig. 2. The cradle 58 is prevented from slipping longitudinally upon the driving shaft 59 by means of a capstan nut 10 screwed upon the front reduced threaded extremity 59h of said shaft 59.

The right hand pulley 55 is an idler pulley and is journaled upon a spindle shaft 1| by means of a pair of ball bearings 12 and 13 located in countersunk sockets 55a and 55h concentrically formed in the ends of said idler pulley 55,

In order to take up any slack and permit adjustment of the sag in the driving belt 53, the

spindle shaft 1| has fitted to its extremities a pair of eccentric bearing bushings 14 and 15 rotatably mounted within a pair of hollow hubs 13 and 11 integral with the free forked end 51 of the swinging cradle 58. The eccentric bushings 14 and 15 are each provided with integral capstan heads 14a and 15a, by means of which said bushings 14 and 15 may be manually rotated in their respective hubs 16 and 11 for either increasing or decreasing the distance between the two pulleys 54 and 55 and consequently adjusting the tension of the driving belt 53, as desired by the operator.

The right hand or inner hub 11 as viewed in Fig. 4 is provided with an upright split lug 18, and a set screw 19 by which means the spindle 1| and the pulley 55 may be locked in adjusted position.

In order to provide a constant upward pressure of the endless belt 53 against the wire being wound on the spool I8, the hub 11 is provided With an integral depending bifurcated lug 80 (see Fig. 3), which is adapted to be connected to a substantially horizontal treadle bar 8|, by means of an upper vertical rod 32 pivoted at its upper end to a pin 22a mounted in said lug 89, and a short hooked rod 83 engaging in an aperture 8 Ia in said treadle bar 8|. The rods 82 and 83 are provided at their adjacent ends with right and left hand threads respectively for receiving a turn buckle 84, for adjusting purposes.

The treadle bar 9| is pvotally connected intermediate its ends to a fulcrum base bracket 85, as by a pin 85a, a pedal 88 being provided at its forward end for engagement by the foot of the operator. The rear end of the treadle bar 8| is provided with a sliding adjustable counter-weight 81 which may be locked in any desired adjusted position, as by a Winged set screw 81a. It will be obvious that by changing the position of the counterweight 81, the pressure of the endless belt 53 against the winding periphery of the spool I8 may be varied at will and after being once adjusted will remain constant throughout the winding regardless of the changing diameter of the spool I8 and its increasing weight of wound wire.

The use of the foot treadle bar 8| greatly facilitates the changing of the spool I8, it being only necessary for the operator to depress the pedal 86 for forcing the treadle bar 8| down to the dotted line position shown in Fig. 3. This will cause the cradle 58 to swing the belt 53 down below the spool flanges 21 and 28 and allow the operator to use both hands for removing the filled spool from and replace the empty spool upon the stud spindles 29 and 30.

Belt traversing mechanism In order to cause the belt 53 to be slowly reciprocated laterally between the spool flanges 21. and 28, for the purpose of preventing tracking of said belt 53 and keeping said belt clean, provision is made of a pair of depending guide fingers 83 and 89 straddling said belt 53 and having their upper ends acustably secured to a horizontal traversing square bar 90 by means of locking screws 88a and 89a. The traversing bar 90 is slidably journaled in a pair of. square bosses 9| and 92, as most clearly shown in Fig. 3. The boss 9| is odset inwardly from the upper extremity of an obliquely extending arm 9|a integral with the hollow hub 3 I. The boss 92 is formed upon the upper end of an oblique arm 92a formed integral with a stationary upstanding bracket 93 secured to the bed plate 33, as by a plurality of. cap screws 93a. The traversing bar 90, intermediate its supporting bosses 9| and 92, is split into two sections which are connected by a right and left adjusting screw 94 having an integral knurled knob 94a for manually adjusting the length of said traversing bar 90, said bar being adapted to be locked in adjusted position by means of a knurled nut 95.

The reciprocating motion of the traversing bar 90 is produced by a rotating circular crank plate 98 pivotally connected to said bar 90 by means of a pitman link 91. The face of the crank plate 98 is provided with a wide diametrical groove 99a, within which is adjustaby fitted a. sliding block member 98 having a protruding crank pin 99 to which the pitman link 91 is pivotally connected.

In order to permit the use of various sizes of winding spools upon the wire spooler, it is necessary to either increase or decrease the travel of the traversing bar 90. This may be accomplished by moving the sliding block 98 nearer or farther from the center point of the groove 96a of the crank plate 96 Within which it is fitted; thus by moving the block 98 closer to the center of. said slot 96a the travel of the traversing bar 90 will be proportionately decreased, while by moving said block 98 farther from the center of said slot the travel of said bar 99 will be proportionately increased.

The circular crank plate 99 is secured to the forward extremity of a rotating shaft transversely journaled in a right angle speed reduction gear unit IOI, said gear unit II'I being driven by means of a grooved cone pulley 02 operatively connected to a double cone grooved driven pulley |03 by means of a. V-belt |04. The double cone driving pulley |03 is preferably connected to one of the upper wire drawing cone pulley shafts of l the wire drawing machine I0, as shown in Fig. 1.

'I'he gear reduction unit |0| is adapted to be supported in a raised oiset position upon the support bracket 34 by mean: of a stationary goose-neck shaped bracket secured to the bed plate 33, as by cap screws |05a.

Wire traversing mechanism In order to cause the wire I2 to be wound upon the spool I8 in successive layers, provision is made of a pair of curved guide fingers |06 extending fcrwardly from an inclined block |01 supported on the end of a short pivot shaft |09. The shaft |08 is adapted to be detachably held within a pair of jaws |59 cf a split clamping member ||0 slidably adjusted upon a horizontal rectangular traversing bar as most clearly shown in Fig. 4. The reciprocating movement of the guide fingers |06 is produced by an upwardly-extending oscillating lever |I2, inter- (IUL) mediately pivoted upon a fulcrum pin I I3 extending rearwardly from the lower end of a. vertical slidingplate II4. The sliding plate ||4 is adjustably mounted on the front face of a gear and cam box I5 fastened to the end walls of the wire machine I as by a pair of integral lugs I I 5a and ||b. (See Fig. 1.) The gear and cam box H5 contains mechanism, not shown, for causing the lever ||2 to cscillate.

One form of such mechanism is fully disclosed in applicants pending application Ser. No. 567,- 585, filed Oct. 8. 1931, and in his prior Reissue Patent No. 16,859 granted Jan. 24, 1928 and forming no part of the present invention,

Power is supplied for operating the mechanism in the box ||5 by means of a horizontal drive shaft IIS suitably journaled in said box ||5 and adapted to be connected by means of a pulley I Il and belt I I8 to the double cone driven pulley |03.

The traversing bar III is adapted to be supported by two pairs of flanged rollers ||9 and |20, the rollers ||9 being rotatably mounted on a pair of bearing studs ||9a secured to the vertical side face of an upright bracket |2| formed integral with the hollow hub pedestal 32. The other pair cf rollers are similarly mounted on a similar pair of bearing studs |20a secured to a bracket |22 formed integral with the rear edge of the base of the stationary bracket 93.

The traversing bar III is coupled to the oscillating lever ||2 by means of a connecting roller |23 mounted upon the side of said bar by a stud pin |24, and adapted to be slidably engaged in a longitudinal slot |25 formed in the lower end of the oscillating lever ||2, as most clearly shown in Fig. 3.

The amount of traverse of the guide fingers |06 may be readily adjusted, while the machine is in operation, by manually rotating a knurled hand wheel |26 mounted upon the top of a vertical screw shaft |21 having threaded engagement with the sliding plate I I4, whereby the fulcrum pin I I3 will be raised or lowered, as desired.

The guide fingers |06 may also be adjusted with respect to the spool flanges 21 and 28 by means of a knurled knob |28 integral with the front end of a horizontal screw shaft |29 having threaded engagement with the split clamping member I I0 for adjusting the same longitudinally upon the traversing bar III. The screw shaft |29 is rotatably journalled in a small bearing block |30 fastened to the front end of the traversing bar n Operation In the operation of changing and replacing a lled wire spool with an empty spool, it is first necessary for the operator to step on the pedal 86 of the treadle bar 8|, which action will cause the cradle 58 and the driving belt 53 to be swung down and away from the spool flanges 21 and 28. The tail stock 42 may next be loosened from its adjusted position on the support shaft 43 by swinging the locking stud operating handle 41 in a counterclockwise direction as viewed in Fig. l, and thereby allowing said tail stock 42 to be pulled forwardly until it abuts against a stop collar 43a secured to the end of said support shaft 43. With the tail stock in its foremost position it may then be swung laterally in a clockwise direction as already described above in the section entitled Winding spool mechanism. This will free the spool I8 from its front supporting stud spindle 29 and also clear the way for sliding the filled spool forwardly off from its rear supporting stud spindle 30.

To insert an empty spool, the above operations are reversed, the tail stock hub 39 being accurately centered with respect to the unlled spool by means of the guide lug 5| and the indexing shaft 52. With the new spool properly adjusted and the wire I2 wound around the periphery of the spool in the usual manner the operator will take his foot oif the pedal 86 permitting the weight 81 to swing the cradle 58 upwardly and bring the driving belt 53 into contact with the spool, causing the latter to rotate at the same Aperipheral speed as the speed of the belt.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specic disclosure but may be modified and embodied in various other forms without departing from its spirit.
